【０００２】
【従来の技術】
例えば実開平7-40507 号公報が示すように、容器体上部にポンプ装置を設けてそのポンプ操作により容器体内液体をノズルから注出するよう設けた容器が広く知られている。
【０００３】
【発明が解決しようとする課題】
上記従来の容器は、通常ステム下端に筒状ピストンを付設し、かつステム上端にノズルを付設した押下げヘッドを嵌合させた作動部材を、容器体内へ垂下したシリンダ内から上方付勢させて起立し、その押下げヘッドから横向きに突出させたノズルから液体を注出できるよう設けているが、容器使用場所によっては、例えば天井壁面へ液状洗剤を噴出させたい場合のように容器体上方へノズルが突出していると便利な場合がある。 しかし従来はノズルが横向きであることを前提としてポンプ操作するよう設けていたから、ノズルを上向きに突出させるとそのポンプ操作が行い難くなる欠点があった。
【０００４】
請求項１記載の容器は、ノズルを上向きに突出させた液体注出容器であって、かつそのポンプ操作を行い易く、又構造が簡易に設けると共にそのポンプ形成部の構成を簡易化するものである。

【０００８】
11は容器体口頸部３の外面へ、頂壁12外周から垂下する周壁13を嵌合させたキャップで、その頂壁後部を隆起部14とすると共に該隆起部の後部から内筒15を起立する。該内筒上部は上向き段部を介して大内径部16とし、かつ内筒下部内には玉弁17による吸込み弁18を設け、更に上記上向き段部やや下方には適当数の透孔19を穿設している。
【０００９】
上記吸込み弁18上方の大内径部16内へは、弁体20を嵌合させて吐出弁21を形成する。弁体20は棒部22上端に外向きフランジ状の弁板23を有し、又棒部上端面から複数の弾性片24を起立して、これ等弾性片上端を水平に設けた押えリング25下面へ付設して形成している。弁板23は内筒上部の大内径部16内径よりやや小内径とし、該弁板を上記上向き段部上へ載置し、このとき棒部22下端は玉弁17のやや上方に位置して該玉弁の盲動を防止可能に設け、又押えリング25上面は内筒の大内径部16上端から僅かに突出するよう設けている。
【００１０】
上記内筒15外面へは外筒31を嵌合させている。該外筒は上記隆起部14上面へ凹凸の係合手段により抜出し不能に嵌合させた帽状部32を下端に付設し、又上端部を内向きフランジ33を介して小径部34としている。上記内向きフランジ33下面が形成する下向き段部へは内筒15の上端面と、弁体20の押えリング25上面とを共に係合させ、既述大内径部16下端の上向き段部と弁板23とで吐出弁21を形成させる。更に外筒31の中間部からは、上記透孔19と連通させて筒35を前上方へ突出し、該筒上端に付設した外向きフランジ状底板36外周部から周壁37を前上方へ突出させて加圧室38を形成し、該加圧室周壁に弾性ドーム状部材39周壁を気密に嵌合させている。
【００１１】
41は既述筒部40付きのキャップ11外面へ嵌合させたカバー筒で、上部横断面を小径に、前壁42は前下方へ傾斜させて、かつ後壁43は垂直に設けて、かつ頂壁44に穿設した透孔に外筒31の上端部を挿通させて上方突出させ、また前壁42に穿設した透孔から弾性ドーム状部材39の頂部を突出させ、さらに周壁45下部をキャップ周壁13の外面へ嵌合させている。 51は筒部40上端に嵌合させた口キャップで、必要により設ければよい。
【００１２】
上記構成において、口キャップ51を外し弾性ドーム状部材39の頂部を押込むと、加圧室38および吸込みおよび吐出の両弁間が形成するポンプ室内は高圧化し、よって弾性片24の弾性に抗して弁板23が押上げられることで吐出弁21が開き、上記ポンプ室内液体が流出する。又弾性ドーム状部材39の頂部を解放すると、その弾性復元により上記ポンプ室内が負圧化し、すると吸込み弁18が開いて容器体内液体がポンプ室内へ流入し、又該液体流入による容器体内の負圧化で、摺動底板５が上昇してその負圧化を解消する。
【００１３】
上記摺動底板５は、吸込み弁18への容器体内液体移送手段を形成するが、該移送手段は図３が示すように、吸込み弁18から吸上げパイプ61を垂下させて形成してもよい。この場合は、液体減少による容器体内負圧化防止のため、容器体口頸部３の上部に外気吸入孔62を穿設し、又口頸部３上端面と、キャップ頂壁12外周部との間に、パッキング兼用として挟持させたフランジ63内周から弾性筒64を垂下し、その弾性筒一部で上記外気吸入孔62内面を閉塞させて外気吸入弁65とすることが出来る。
既述各部材は、それぞれ合成樹脂材で形成している。但し弾性ドーム状部材34はゴムでもよく、玉弁は金属ないしセラミック製とすることが出来る。
【００１４】
